Patent BG-50580-A1 (BG)
Title: Method for technilogical objects control
Inventor: NAPLATAROV KONSTANTIN KH
IPC: G05B13/02
Filed: 1988-07-18
Abstract: This method is used to control technological facilities, such as heating furnaces, chemical reactors, steam cauldrons, etc. It enhances accuracy and swiftness while reducing the expenditures in the saving agent : fuel or materials. The method helps to determine whether each transition process is prompted by a change in the assignment, or is due to disturbances, while the managing impact consists of two components. One of them is formed following the proportional-integral law and has an uninterrupted action, while the other comes on impulse. The impulses are with maximum permissible value with the respective polarity, while their duration is different for the two types of transition processes, depending on the starting conditions and the dynamics of the facility, and is proportionate to the relative expenditure of the main agent, the mistake and the first derivative of the leading value. The ratio coefficients are selected so that the transition processes are critically periodic.

Abstract: The method and device are applied in individual positioning devices, robots, etc. It creates an opportunity for an wider speed variance, enhances the dynamics in management, ensures an individual use of positioning and inclusion to a standard service amplifier. Under the method, the speed is navigated, by summing voltage proportionately to real speed, and an adjusting signal, derived digitally by a second contour of management. The pre-set speed in analogous form connects with the plug setting the speed, while the outgoing signal from summation connects with the entry for tachogenerator of a standard servoamplifier. The device contains a source for speed setting (1), a summing amplifier (2), resistors (3,5), an impulse transformer of a pulse coder (4), digital-analogous transformer (6), a reversive counter (7), a generator (8) and a transformer for speed setting (9).<IMAGE>

Title: Remote-controlled receiver with resupply of energy to battery
Inventor: THUS FRANCISCUS J M
IPC: H04B10/80
Filed: 1989-10-27
Abstract: F. Abstract: "Remote-controlled receiver with resupply of energy to battery."     In a receiver for use in a remote-control system in which messages are radio-transmitted by means of infrared light, the receiving photodiode circuit is of the forward-biased type and is connected in the forward direction between ground and a voltage which is lower than the knee voltage of the photodiode circuit. As a result, a photocurrent IpO is supplied by the photodiode circuit itself. The low-frequency component of this photocurrent can now be utilized as a charge current for a rechargeable battery. Its lifetime will thus be considerably longer.

Title: Manufacture of composite web having absorbent properties
Inventor: ISKRA MICHAEL J
IPC: D04H1/64
Filed: 1990-03-21
Abstract: ABSTRACT OF THE DISCLOSURE A method of dispersing droplets of a polymerizable, cross-linkable material, in a liquid carrier, within a fibrous web, in which the material is to be polymerized and cross-linked, as a part of a method of manufacturing a composite web, which comprises the fibrous web and dispersed inclusions of the material, as polymerized and cross-linked. Droplets of the material are dispersed within the fibrous web by moving the fibrous web through a droplet-flicking zone and flicking droplets of the material, in the liquid carrier, onto opposite sides of the fibrous web as the fibrous web is moved through the droplet-flicking zone.  On each of opposite sides of the fibrous web, a rotating brush has bristles, picking up the material, in the liquid carrier, and flicking droplets thereof as the brush rotates.  Each brush picks up the material, in the liquid carrier, from a rotating roller wiped by the bristles of such brush.  Each brush and the roller wiped by the bristles of such brush rotate, in opposite rotational senses, about parallel axes.  The material is polymerized and cross-linked in situ, so as to form the composite web.

Title: Method for displaying kanji characters
Inventor: SCHILLER STEPHEN N
IPC: B41B19/01
Filed: 1990-05-11
Abstract: This invention relates to a method for displaying characters on a screen or printer, particularly kanji characters.      The structure of the character is represented by stems and counters, bath vertical and horizontal, the counters being the spaces between stems. The character is then transferred from character to display space. Either the horizontal or vertical counters are grouped into a first chain of counters. The non-integral counter widths of this chain are adjusted in relation to the other counter widths within the chain, selected counter widths being made equal to others within the chain in order to most faithfully reproduce the desired character. The remaining horizontal or vertical counters, if any, are also grouped into one or more series of chains which are also adjusted, chain by chain. Then the orthogonal set of counters are adjusted in the same way. The widths of the stems themselves may also be adjusted to more faithfully represent the character in the scale at which it will be displayed.
